DETAILED DESCRIPTION

Computing devices typically include one or more interface devices to accommodate input and/or output. In some examples, the computing devices are designed and/or otherwise provisioned to interact with one or more users, in which a visual and/or audio interface device facilitates one or more functions of a user interface (UI). Example UIs include, but are not limited to, touchscreen input devices, mouse pointer devices, and visual display devices to render video information to the user. Example visual display devices include, but are not limited to, a cathode ray tube (CRT) display, a light emitting diode (LED) display, a liquid crystal display (LCD), in which one or more of the aforementioned display devices may include touch control (e.g., an ability to control a mouse cursor of an operating system without a mouse device).

Traditional display devices, including examples disclosed above, include a physically rigid viewing area having a particular screen size (e.g., a set spatial dimension) that is established at the time the display device is manufactured. For example, traditional display devices have a display size having a width value, a height value, a total viewable area value and/or a diagonal length value. In some examples, the diagonal length value is provided by a manufacturer that indicates a length between two opposite screen corners, and an aspect ratio indicating a ratio of the horizontal length to a vertical length is provided. At the time of this writing, display devices typically have aspect ratios of 4:3, 5:4, 16:10 and 16:9, but example methods, systems and apparatus to manage a spatially dynamic display are not limited thereto. While traditional display devices, such as those described above, include a spatial dimension with a rigid viewing surface that is established at the time of manufacture, example methods, systems and apparatus disclosed herein manage display behavior for physically alterable displays that exhibit spatially dynamic properties.

Physically alterable displays that have spatially dynamic properties (sometimes referred to herein as a “dynamic display,” or a “spatially adjustable display”) include display devices that have two or more viewing areas for rendering visual information. In some examples, a dynamic display has a first length dimension and a first width dimension that results in a first viewable area for a user. However, the dynamic display may be manipulated to change the first length dimension to a second length dimension, and/or change the first width dimension to a second width dimension, thereby resulting in a second viewable area for a user. In some examples, the dynamic display is flexible such that the flexible display may wrap around itself in a generally cylindrical shape. In other examples, a portion of the dynamic display that is not viewable (e.g., a portion that is wrapped around itself) may be turned off to reduce energy that would otherwise be wasted on that non-viewable portion. In still other examples, the dynamic display is spatially modified by one or more folding operations to either increase or decrease a viewable area for the user.

Example spatially dynamic displays, such as flexible displays and/or foldable displays, may be used with any type of computing device, such as desktop computers, laptop computers, mobile telephones, e-readers and/or tablet computing devices. In some examples, the dynamic display associated with the computing device has a first viewing area at a first time, but the user manipulates (e.g., by rolling the display, by folding the display, etc.) the dynamic display at a second time to cause a second viewing area at a second time. Example methods, systems and apparatus disclosed herein detect such contextual changes to the dynamic display viewing area to manage one or more alternate image output signals of the dynamic display device. For example, if the first viewing area at the first time is larger than the second viewing area at the second time (e.g., the user caused a reduction in the viewable area by rolling a portion of the dynamic display device around itself, or by folding a portion of the dynamic display under itself), then example methods, systems and apparatus disclosed herein manage the image output signals to the dynamic display device to conform to a display configuration better adapted to the second viewing area.

In some examples, managing the image output signals are dynamically adjusted to fit within an available screen area of the dynamic display device in response to physical changes of the screen area. The image output signals associated with a first available screen area may have icons and text that, in response to a change from a first available screen area to a second available screen area, are increased or decreased in size to better fit to the second available screen area. In other examples, one or more icons may be associated with a priority value to indicate a relative importance with other icons. In operation, an example icon with a relatively higher priority value will be preserved for rendering on the dynamic display device when the available screen area decreases. One or more icons with relatively lower priority values are removed to accommodate rendering of the icons having the relatively higher value, and a link icon may be rendered to allow access to the icons associated with the relatively lower priority value. In some examples, icons having a relatively highest priority value are referred to herein as primary icons, and icons having a relatively lower priority value are referred to herein as secondary icons, tertiary icons, etc.

FIG. 1A is an example system 100 to manage a spatially dynamic display. In the illustrated example of FIG. 1A, the system 100 includes a central housing 102 connected to a spatially dynamic display 104 that can be manipulated via a screen area adjustment handle 106. The example central housing 102 of FIG. 1A is illustrated with a generally cylindrical shape to allow the example spatially dynamic display 104 to wrap around a central storage axis 108 for storage. While some of the examples disclosed herein include a spatially dynamic display that is flexible, example methods, apparatus, systems and/or articles of manufacture disclosed herein are not limited thereto. For instance, some example spatially dynamic displays may be a relatively rigid material having one or more foldable portions. In some examples, each of the foldable portions are separated and/or otherwise partitioned by a bendable crease that, when folded by a number of degrees (e.g., 90 degrees, 180 degrees, etc.), causes the aggregate area of the spatially dynamic display to decrease.

Continuing with the example flexible-type spatially dynamic display 104 of FIG. 1A, in the event the example screen area adjustment handle 106 is pulled in a direction to the right of the example central housing 102 along a viewing axis 109, then the example spatially dynamic display 104 will unwind from the central storage axis 108 to increase a viewable area (lengthen). Portions of the example spatially dynamic display 104 that are wrapped around the central storage axis 108 are not viewable to a user (e.g., non-visible portions of the spatially dynamic display 104), while portions of the example spatially dynamic display 104 that have been unwound from the central storage axis 108 may be viewed by a user along the viewing axis 109. Storage of the example spatially dynamic display 104 may occur by winding a shaft (not shown) attached to the example central storage axis 108 in a clockwise or counterclockwise direction. In some examples, the central storage axis 108 may be mechanically connected to a spring (e.g., a coil spring) to forcibly bias the spatially dynamic display 104 toward and around the central storage axis 108. The example spring bias causes a force on the example spatially dynamic display 104 in a direction toward the example central housing 102 (i.e., toward the left). In other words, in some examples the viewable portion of the example spatially dynamic display 104 along the example viewing axis 109 toward the central housing 102 and wrap around the central storage axis 108 when not in use.

The example spatially dynamic display 104 has a maximum length (L_(MAX)) that, when reached by pulling the example screen area adjustment handle 106 in a rightward direction from the example central housing 102, results in a maximum viewable area of the spatially dynamic display 104. When the example spatially dynamic display 104 is fully extended (e.g., pulled-out) from the example central housing 102, then a computing device communicatively connected to the example spatially dynamic display 104 may render a particular screen configuration based on the available area of the dynamic display 104. In some examples, the particular screen configuration associated with the fully extended (L_(MAX)) spatially dynamic display 104 reveals a maximum number of icons. In the illustrated example of FIG. 1A, the spatially dynamic display 104 renders a maximum of twenty-five (25) icons in columns A through E and rows A through E. As described in further detail below, one or more display configuration models may be invoked in response to a change in the available display area of the example spatially dynamic display 104, in which one or more icons may be prioritized to remain in the remaining viewable area when the dynamic display 104 is retracted by a certain length (e.g., less than the length L_(MAX)).

In some examples, a relatively smaller size of the spatially dynamic display 104 is desired. In the illustrated example of FIG. 1A, the spatially dynamic display includes a first reduction zone 110 and a second reduction zone 112. If the example spatially dynamic display 104 is retracted by a length equal to the example first reduction 110 (L_(RED-1)), example methods, systems and/or apparatus disclosed herein dynamically adjust the visual configuration of the spatially dynamic display based on the reduced area caused by the retraction. Similarly, if the example spatially dynamic display 104 is retracted by a length equal to the example first reduction 110 and the example second reduction 112 (L_(RED-2)), example methods, systems and/or apparatus disclosed herein dynamically adjust the visual configuration of the spatially dynamic display based on the reduced area caused by the retraction, as described in further detail below. While the illustrated example includes two reduction zones, examples disclosed herein are not limited thereto. In some examples, the spatially dynamic display 104 may operate between any length between the maximum extension (L_(MAX)) and a fully closed position, in which the entire spatially dynamic display 104 is retracted within the central housing 102.

In the event the example spatially dynamic display 104 is retracted by a length associated with the example first reduction 110, then the example icons in columns D and E will not be visible. Example methods, systems, apparatus and/or articles of manufacture disclosed herein dynamically modify the visual configuration as the spatially dynamic display 104 changes in length (e.g., as the spatially dynamic display increases in length from zero to L_(MAX) and/or as the spatially dynamic display decreases in length from L_(MAX) to zero). In the illustrated example of FIG. 1A, icons associated with “App 2,” “App 20” and “App 25” are assigned with a primary priority 114, “App 6,” “App 12,” “App 14,” “App 16,” “App 19,” “App 21” and “App 22” are assigned with a secondary priority 116, and the remaining icons are assigned with a default tertiary priority. Generally speaking, one or more icons assigned with a primary priority, as compared to a secondary and/or tertiary priority, are indicative of a relatively greater importance to a user of a computing device, such as applications and/or programs that are used with a relatively greater frequency.

Continuing with the example in which the example spatially dynamic display 104 is reduced by a length associated with the first reduction 110 (L_(RED) _(_) ₁), example methods, systems, apparatus and/or articles of manufacture disclosed herein adjust the visual configuration of the remaining visible portion(s) of the spatially dynamic display 104 to render icons associated with the primary priority 114. In the event the area of the spatially dynamic display 104 has remaining space after the icons associated with the primary priority 114 are rendered, icons associated with the secondary priority 116 are arranged on the dynamic display 104 for rendering, as shown in FIG. 1B.

In some examples, portions of the spatially dynamic display 104 that have been retracted to the central housing 102 are powered off. In other words, because the example portions of the spatially dynamic display 104 stored in the central housing 102 are not visible, the example source image adjustor 306 sends one or more instructions to an example video controller to disable such non-visible portions of the spatially dynamic display. In the illustrated example of FIG. 1B, the spatially dynamic display 104 has been reduced in length L₁ (and corresponding area) by the first reduction 110, and icons associated with the primary priority 114 and secondary priority 116 have been rendered at the expense of the relatively lower assigned icons. However, a link button 118, when selected (e.g., via a touch-screen input, mouse click, etc.), causes one or more relatively lower priority icons to be displayed.

FIG. 1C illustrates the example system 100 after the example spatially dynamic display 104 has been retracted by an additional length associated with the example second reduction 112. In the illustrated example of FIG. 1C, the visual configuration of the spatially dynamic display 104 is modified to render the highest priority icons 114, and the link button 118, when selected, causes one or more relatively lower priority icons to be displayed. As described above, examples disclosed above include three distinct positions of the spatially dynamic display 104, but example methods, systems, apparatus and/or articles of manufacture are not limited thereto. In some examples, dynamic modification of the visual configuration of the spatially dynamic display 104 occurs as it is retracted or extended from the central housing 102. Additionally, while the example central housing 102 is shown having a generally cylindrical shape, example methods, systems, apparatus and/or articles of manufacture disclosed herein are not limited thereto. In some examples, the central housing 102 is integrated with a computing device, such as a mobile telephone, personal computer, etc. In still other examples, the computing device may be integrated within the central housing 102. In other examples, the spatially dynamic display 104 changes a display size by one or more folds. In such examples, the spatially dynamic display 104 may be a rigid material rather than a relatively flexible material capable of rolling and/or otherwise winding around itself. The example foldable spatially dynamic display 104 may, when folded at one or more locations, cause the visual configuration of the spatially dynamic display 104 to change in the manner disclosed above in connection with FIGS. 1A-1C.

FIG. 2 illustrates additional detail of the example system 100 to manage the spatially dynamic display 104 of FIGS. 1A-1C when the spatially dynamic display 104 is constructed of a flexible material to be stored and/or used in one or more rolled/wrapped orientations 200, or when the spatially dynamic display 104 is constructed of a foldable material to be stored and/or used in one or more fully unfolded, partially folded or completely folded orientations 250. In the illustrated example of FIG. 2, the central housing 102 is communicatively connected to a computing device 202. The example computing device 202 may include, but is not limited to, a personal computer (e.g., a laptop, a desktop, etc.), a personal digital assistant, an e-reader, a mobile telephone, etc. While the computing device 202 of the illustrated example of FIG. 2 is shown as a separate entity from the central housing 102, examples disclosed herein are not limited thereto. In some examples, the computing device 202 is integrated into the central housing 102, or vice-versa. The example computing device 202 of FIG. 2 includes a video input/output (I/O) module 204 to control a visual output of the example spatially dynamic display 104 and, in some examples, respond to inputs from the spatially dynamic display 104 in the event it includes touch-screen capabilities.

The example video I/O module 204 may be an industry standard video card capable of rendering visual output based on inputs from an operating system and/or other inputs. The computing device 202 of FIG. 2 includes a dynamic display size manager 205 that is communicatively connected to the video I/O module 204 and the central housing 102. In some examples, the dynamic display size manager 205 is communicatively connected to a rotary shaft encoder 206 to determine an angular position of the central storage axis 108, which is indicative of how much of the spatially dynamic display 104 is available for viewing. In some examples, the rotary shaft encoder 206 is not used and, instead, one or more alternate techniques of determining the available viewing area are employed. For example, the central housing 102 may include a length marker sensor 208 that detects one or more delineated length markers 210, such as a first length marker 210A and a second length marker 210B attached to the example spatially dynamic display 104. Any number of length markers 210 may be attached (e.g., embedded) to the example spatially dynamic display 104 in a number of linear positions, and the example length markers 210 may be employed for use with the flexible rolled/wrapped orientation 200 and/or the foldable orientation 250. In some examples, a number of length markers 210 are embedded in the spatially dynamic display 104 in equally-spaced linear positions along the viewing axis 109. In response to the example length marker sensor 208 detecting a first length marker 210A, the example dynamic display size manager 205 may invoke one or more modifications of the visual configuration of the example spatially dynamic display 104. In particular, detecting the first length marker 210A is indicative of a portion of the example spatially dynamic display 104 that can be viewed by a user. Similarly, in response to the example length marker sensor 208 detecting a second length marker 210B, the example dynamic display size manager 205 may invoke one or more modifications of the visual configuration tailored to the alternate viewing area of the example spatially dynamic display 104.

Similarly, the example first length marker 210A and the example second length marker of the foldable orientation 250 may provide an indication of the available screen size to be used and/or otherwise energized for viewing purposes. For example, the first length marker 210A detects when a first fold portion 252 of the foldable spatially dynamic display 104 is unfolded or folded. Similarly, the example second length marker 210B detects when a second fold portion 254 of the foldable spatially dynamic display 104 is unfolded or folded.

FIG. 3 illustrates additional detail of the example dynamic display size manager 205 of FIG. 2. In the illustrated example of FIG. 3, the dynamic display size manager 205 includes a display size monitor 302, a source image comparator 304, a source image adjuster 306, a prioritizer 308, a link generator 310 and a configuration model storage 312. In operation, the example display size monitor 302 determines an available viewable screen area of the example spatially dynamic display 104 by capturing and/or otherwise retrieving screen extraction length information or information indicative of which fold portions (e.g., the first fold portion 252, the second fold portion 254) are folded (closed) or unfolded (open). As described above, screen extraction length information may be determined by information retrieved from the example encoder 206, the example length marker sensor 208, or any other sensor indicative of how much available viewing area can be used and/or otherwise consumed by a user of the example system 100. Based on the determined available viewing area information captured by the example display size monitor 302, the example source image comparator 304 compares the available viewing area information to the example configuration model settings storage 312 to determine visual configuration instructions to be sent to the example video I/O module 204. The example configuration model settings storage 312 may store one or more configurations settings that differ based on an exposed length of the example spatially dynamic display 104.

FIG. 4 is an example spatial/visual configuration table 400 that may be stored in the example configuration model settings storage 312 and accessed by the example source image comparator 304. In the illustrated example of FIG. 4, the table 400 includes an exposed length column 402, a primary icon column 404, a primary icon size column 406, a secondary icon column 408, a secondary icon size column 410, a tertiary icon column 412, a tertiary icon size column 414 and a link button column 416. The example prioritizer 308 of FIG. 3 is employed during one or more configuration sessions (e.g., a user-initiated configuration, a factory-initiated configuration, etc.) to assign each icon with a corresponding primary, secondary, tertiary, or other priority designation. Additionally, the example prioritizer 308 identifies icon display priorities associated with a template and/or display model, such as an example table 400. The exposed length column 402 in the illustrated example of FIG. 4 includes three length values; one that reflects a full (maximum) viewing potential (e.g., 9.6 inches), one that reflects a reduction associated with the first reduction 110 (e.g., 6.4 inches), and one that reflects a reduction associated with the combined first reduction 110 and the second reduction 112 (e.g., 3.2 inches). Each of these three example display modes may be invoked by the example source image adjuster 306 based on a corresponding length marker 210 detected by the example length marker sensor 208. While the illustrated example table 400 of FIG. 4 includes three (3) delineated viewing modes, examples disclosed herein are not limited thereto. In some examples, the source image adjuster 306 may respond to different degrees of granularity in response to changing length values detected by the encoder 206, such as causing image adjustments at increments of 1 millimeter, or any other increment value of interest.

If the example display size monitor 302 retrieves an indication that the example spatially dynamic display 104 is extended 9.6 inches (e.g., a maximum extension for the example spatially dynamic display 104 of FIGS. 1A-1C and 2), which is reflected in a first row 420 of FIG. 4, then the example table 400 includes information indicative of which icons are authorized for display and corresponding sizes (e.g., size in pixels) for each authorized icon. In the illustrated example of FIG. 4, the first row 420 indicates that all icons having a primary priority are authorized to be displayed (see column 404) with an icon dimension of 16×16 pixels (see column 406). The example first row 420 also indicates that all secondary and tertiary icons are authorized for display having corresponding dimensions of 16×16 pixels. In some examples, a link button is unnecessary because the available viewable screen area of the spatially dynamic display 104 is large enough to accommodate all desired icons. As such, the example link button column 416 indicates a “No” value to prevent a request to include a link button on the dynamic display 104 when the exposed screen length is at a value of 9.6 inches.

If the example display size monitor 302 retrieves and/or otherwise receives an indication that the example spatially dynamic display 104 changes to an alternate extension length, such as from the example fully extended 9.6 inches to 6.4 inches, then the example source image comparator 304 is invoked by the display size monitor 302 to determine corresponding display parameters. In the illustrated example of FIG. 4, the table includes a second row 422 having information indicative of which icons are authorized for display and corresponding sizes for each authorized icon. In the illustrated example of FIG. 4, the second row 422 indicates that all icons having a primary priority are authorized to be displayed (see column 404) with an icon dimension of 32×32 pixels (see column 406). The example second row 422 also indicates that all secondary icons are authorized for display (see column 408) with an icon dimension of 16×16 pixels (see column 410). However, the example second row 422 indicates that no tertiary icons are authorized for display (see column 412), but a link button 118 is authorized and/or otherwise rendered on the viewable portion of the spatially dynamic display 104 for presentation to the user (see column 416). As described above, the example link button 118 is rendered when one or more of the icons have been hidden from view due to their relatively lower priority value. The link button 118, when selected, causes the hidden icons (e.g., relatively lower priority icons) to be displayed in lieu of the icons authorized by display based on the example table 400. In other words, when the example link button 118 is selected, any secondary and/or tertiary icons may be rendered on the example spatially dynamic display 104.

If the example display size monitor 302 retrieves and/or otherwise receives an indication that the example spatially dynamic display 104 changes to an alternate extension length associated with a reduction of both the first reduction zone 110 and the second reduction zone 112, thereby leaving 3.2 inches of available viewing, then the example source image comparator 304 is invoked by the display size monitor 302 to determine corresponding display parameters. In the illustrated example of FIG. 4, the table includes a third row 424 having information indicative of which icons are authorized for display and corresponding sizes for each authorized icon. In the illustrated example of FIG. 4, the third row 424 indicates that all icons having a primary priority are authorized to be displayed (see column 404) with an icon dimension of 32×32 pixels (see column 406). The example third row 424 also indicates that no secondary or tertiary icons are authorized for display (see columns 408 and 412, respectively), and that the link button 118 is authorized for rendering (see column 416).

While an example manner of implementing the dynamic display size manager 205 of FIG. 3 is illustrated in FIGS. 1A-1C, and 2-4, one or more of the elements, processes and/or devices illustrated in FIGS. 1A-C and 2-4 may be combined, divided, re-arranged, omitted, eliminated and/or implemented in any other way. Further, the example display size monitor 302, the example source image comparator 304, the example source image adjuster 306, the example prioritizer 308, the example link generator 310, the example configuration model settings storage 312, the example encoder 206, the example length marker sensor and/or, more generally, the example dynamic display size manager 205 of FIGS. 1A-1C and 2-4 may be implemented by hardware, software, firmware and/or any combination of hardware, software and/or firmware. Thus, for example, any of the example display size monitor 302, the example source image comparator 304, the example source image adjuster 306, the example prioritizer 308, the example link generator 310, the example configuration model settings storage 312, the example encoder 206, the example length marker sensor and/or, more generally, the example dynamic display size manager 205 of FIGS. 1A-1C and 2-4 could be implemented by one or more analog or digital circuit(s), logic circuits, programmable processor(s), application specific integrated circuit(s) (ASIC(s)), programmable logic device(s) (PLD(s)) and/or field programmable logic device(s) (FPLD(s)). When reading any of the apparatus or system claims of this patent to cover a purely software and/or firmware implementation, at least one of the example display size monitor 302, the example source image comparator 304, the example source image adjuster 306, the example prioritizer 308, the example link generator 310, the example configuration model settings storage 312, the example encoder 206, the example length marker sensor and/or, more generally, the example dynamic display size manager 205 of FIGS. 1A-1C and 2-4 is/are hereby expressly defined to include a tangible computer readable storage device or storage disk such as a memory, a digital versatile disk (DVD), a compact disk (CD), a Blu-ray disk, etc. storing the software and/or firmware. Further still, the example display size manager 205 of FIGS. 2 and 3 may include one or more elements, processes and/or devices in addition to, or instead of, those illustrated in FIG. 3, and/or may include more than one of any or all of the illustrated elements, processes and devices.

A flowchart representative of example machine readable instructions for implementing the dynamic display size manager 205 of FIGS. 2 and 3 is shown in FIG. 5. In this example, the machine readable instructions comprise program(s) for execution by a processor such as the processor 612 shown in the example processor platform 600 discussed below in connection with FIG. 6. The program(s) may be embodied in software stored on a tangible computer readable storage medium such as a CD-ROM, a floppy disk, a hard drive, a digital versatile disk (DVD), a Blu-ray disk, or a memory associated with the processor 612, but the entire program(s) and/or parts thereof could alternatively be executed by a device other than the processor 612 and/or embodied in firmware or dedicated hardware. Further, although the example program(s) is/are described with reference to the flowcharts illustrated in FIG. 5, many other methods of implementing the example dynamic display size manager 205 may alternatively be used. For example, the order of execution of the blocks may be changed, and/or some of the blocks described may be changed, eliminated, or combined.

As mentioned above, the example process of FIG. 5 may be implemented using coded instructions (e.g., computer and/or machine readable instructions) stored on a tangible computer readable storage medium such as a hard disk drive, a flash memory, a read-only memory (ROM), a compact disk (CD), a digital versatile disk (DVD), a cache, a random-access memory (RAM) and/or any other storage device or storage disk in which information is stored for any duration (e.g., for extended time periods, permanently, for brief instances, for temporarily buffering, and/or for caching of the information). As used herein, the term tangible computer readable storage medium is expressly defined to include any type of computer readable storage device and/or storage disk and to exclude propagating signals and to exclude transmission media. As used herein, “tangible computer readable storage medium” and “tangible machine readable storage medium” are used interchangeably. Additionally or alternatively, the example process of FIG. 5 may be implemented using coded instructions (e.g., computer and/or machine readable instructions) stored on a non-transitory computer and/or machine readable medium such as a hard disk drive, a flash memory, a read-only memory, a compact disk, a digital versatile disk, a cache, a random-access memory and/or any other storage device or storage disk in which information is stored for any duration (e.g., for extended time periods, permanently, for brief instances, for temporarily buffering, and/or for caching of the information). As used herein, the term non-transitory computer readable medium is expressly defined to include any type of computer readable storage device and/or storage disk and to exclude propagating signals and to exclude transmission media. As used herein, when the phrase “at least” is used as the transition term in a preamble of a claim, it is open-ended in the same manner as the term “comprising” is open ended.

The program 500 of FIG. 5 begins at block 502 where the example display size monitor 302 acquires an indication of an available display size of the example spatially dynamic display 104. As described above, an indication of the available display size that can be used (e.g., capable of being viewed by a user) may be determined by reading a rotary encoder value and/or detecting particular portions of the dynamic display 104 based on length markers 210 detected by the example length marker sensor 208. In still other examples, an indication of the available display size that can be used is determined by reading the length markers 210 to determine whether one or more fold portions (e.g., the first fold portion 252, the second fold portion 254, etc.) are either unfolded, partially folded, or completely folded. The acquired indication of available size is provided to the example source image comparator 304, which queries the example configuration model settings storage 312 to determine how the visual configuration of the example spatially dynamic display 104 should be changed (block 504). As shown in the example table 400 of FIG. 4, the indication of the available display size may be retrieved from the example display size monitor as an exposed length value (e.g., in centimeters, in millimeters, in inches, in pixels, etc.).

Based on the example source image comparator 304 identifying a match between the retrieved indication of available display area and a configuration setting in the example model settings storage 312, the example source image adjuster 306 sends one or more control signals to the example video I/O module 204 of the computing device 202 with which the spatially dynamic display 104 is attached (block 506). If the example display size monitor 302 does not identify an indication that the screen size has changed (block 508), then the example program 500 of FIG. 5 waits for such an occurrence. When an indication of a screen size change occurs (block 508), control returns to block 502 to retrieve the current available screen viewing area value.
